Upon receipt of a signal indicating occurrence of anomalies, an information processor displays the nature of the anomalies. The information processor accepts for each anomaly, an input operation for assignment of a worker who is to handle an anomaly. Based on the assignment, the information processor notifies a terminal device of the worker of the nature of the anomaly to be handled by the worker. The terminal device displays contents of a remedy for the anomaly. The terminal device transmits progress information to the information processor. The information processor displays the progress information. The information processor further accepts an input operation for updating the assignment of a worker who is to handle the anomaly. Based on the assignment updated, the information processor notifies the terminal device of the worker of the nature of the anomaly to be handled by the worker.

A method for operating cycle-oriented control software for controlling processes, wherein the software executes within a runtime environment on a computer system and uses two independent time bases: a first time base derived from a hardware timer, and a second time base provided by a another timer is transmitted via a network communication, and the second time base is provided via telegrams with time stamps, where a receive routine assigns time stamps to a receipt time and stores them in a buffer, an evaluation routine recognizes and compensates interrupts that disrupt the safe time base, the past values of the first time base are stored in a cyclical buffer that an interrupt handler periodically updates, the evaluation routine checks the time differences between the telegrams and corrects the second time base if required, such that reliable and safe time measurement are ensured, even in the event of system management interrupts.
